The cell membrane is selectively permeable, which means...

• All materials can enter and leave the cell

• Certain things can enter while others cannot

• The cell manually sorts through all materials

Osmosis is the movement of _____ across a membrane.

• food
• energy
• oxygen
• water

During osmosis

• water moves from high to low concentration
• large or oddly shaped molecules move across a cell membrane
• water moves when energy is used
• proteins are built

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

• Osmosis
• Diffusion
• Equilibrium
